CASTING HOOKS INTO EYES.

SPECIFICATION forming part of Letters Patent No. 390,907, dated October9, 1888.

Application filed April 5, 1888. Serial No. 269,691. (Modeh) T (ZZZ whomit nuig concern:

Be it known that I, CHARLES L. SAGE, a citizen of.the United States,residing at Middletown, in the county of Middlesex and State ofConnecticut, haveinvented new and useful Improvements in Casting Hooksinto the Eyes of Pulley-Blocks and other Articles, of which thefollowing is a specification.

This invention relates to a method of form- [0 ing castings by whichhooks can be cast into eyes, so as to form a durable con nection, ashereiuafter set forth and claimed, and illustrated in the accompanyingdrawings, in which- Figure 1 is a side elevation of an eye with a hook.Fig. 2 shows a sand pattern for casting an eye. Fig. 3 shows a core-boxwith sand core and a cast eye. Fig. 4 shows a detail view of a sandcore. Fig. 5 shows asand pattern with cavities corresponding to the eye,

the sand core, and the hook. Fig. 6 shows a sand pattern and core withhook cast into the eye. Fig. 7 is a section in the plane 9000, Fig. (3.Fig. 8 shows a sand pattern with cavities corresponding to the eye, thehook, and an object to be cast onto the eye. Fig. 9is a sectional viewof a hook and an eye with an ohjeot attached thereto before removal fromthe sand pattern. Fig. 10 is a section in the plane 11y, Fig. 8.

In the drawings, the letter A indicates an eye having a shank, O. Alink,B, of a hook,

D, is shown cast into the eye. The eye A, with its shank O, is cast inany ordinary way, as by a sand pattern, Fig. 2. The eye and shank arethen placed into a eore'box, N, made in two sections and formed so as toaccommodate the eye and shank and to leave a space which, when filledwith sand, will form the sand core F, Fig. 4, having the groove G,formed by part 40 of the eye A, and a groove, H, formed by the core-boxN, and which groove H is to receive the metal for the link B, as will behereinafter shown. The parts ofthe core-box N are formed in anywell-known way, and tongues or de- 5 pressions O on one part of thecore-box will serve for the engagement of depressions or tongues on theother part of the core-box.

In Fig. 5 is shown a pattern having a part, J, corresponding to theshank O, a part, I, cor- 5o responding or partly corresponding to theeye A, a part, K, corresponding to the link B, a

part, L, corresponding to the hook D, and a part, M, corresponding tothe sand core F. This pattern is pressed into sand, so as to form a sandpattern or cavity, as indicated in Fig. 5. Into this cavity are placedthe shank (1, eye A, and sand core F, so as to leave a space which, whenfilled with molten metal, will form the link B and hook D. The moltenmetal, when poured into the sand core, will flow into the groove H inthe sand core and into the cavities in the sand, so as to form the linkB and hook D, as indicated in Fig. 7. When the metal has becomesufficiently hard or set, the sand core and sand are removed, leavingthe link and eye interlocked or linked together.

The shank O can be utilized in various ways as, for example, in Fig. 1,where a shell, E, for i a pulley-block is shown cast or secured to the lshank O. In place ofa pulley-block shell, any other object may besecured to the eye-such, for example, as a base-plate orattachingplatefor securing the eye A to any suitable place-as, forexample, to a rafter or othersupport.

To cast an object-such as a shell, E-to the eye A, a pattern is pressedinto sand, as seen in Figs. 8 and 10, said pattern having the parts J IK L, corresponding to the parts J I K Lof 8o Fig. 5, and also having theform P for the shell B, with the hook I), are then placed into theproper cavities, as seen in Fig. 9, and the cavity formed by the part P,Fig. 8, being filled with molten metal, the shell E will be formed andwill adhere to the eye A orits shank O, as seen in Fig. 9.

I am aware of the Letters Patent No. 47,656, and do not wish to beunderstood as claiming the method therein described and shown forcasting an eye into the eye of a hook. It will be seen that according tomy invention the previously cast eye A is embedded in the sand core F,and the latter is thereby supported internally by the said internal eyeor ring, A, which fits a semicircular passage within the core, theobject of which is to sustain the core and prevent it from crumbling upwhen the stream of molten metal is poured :00 upon the core for castingthe eyeor link B of the hook D in the eye or ring A. In this re- E. Theeye A, with its shank G, and the link l l i spect my invention diilers,essentially, from prior methods, where the sand core isunsupportedinternally. Asand core of about threequarters of an inch indiameter unsupported 5 internally will not withstand the action of astream of molten metal poured around it and into a groove'within it, asin the patent mentioned. By internally supporting the core F by theinternal eye or ring, A, embedded therein, according to my invention,the core is sustained, as before stated, and will not crumble up whenthe eye of the hook is cast around it.

Vhat I claim is 1. The method, substantially as herein described, ofcasting hooks into eyes, which eonsists in first casting the eye, thenforming on the eye a sand core, so that the eye constitutes an interiorsupporting'bar for the sand core, then forming a pattern correspondingto the hook, the sand core, and the eye, then pressing this pattern intosand to form a corresponding cavity, then placing the eye, with the sandcore, into the part of the cavity corresponding to 5 the eye and sandcore, and casting the hook with its link extending round the sand core.

2. The method, substantially as herein de scribed, of casting a hookinto an eye and se curing an object to said eye, which consists in ,ocasting the eye, forming on the eyea sand core,

so that the eye constitutes an interior supporting-bar for the sandcore, forming a pattern corresponding to the hook, the sand core, and

the eye, pressing this pattern into sand to form a corresponding cavity,placing the eye, with the sand core, into the part of the cavitycorresponding to the eye and sand core, casting the hook with its linkextending round the sand core, and securing to the eye a suitableobject-such as a pulley-block shell.

3. The method, substantially as herein described, ofcasting a hook intoan eye and casting an object onto said eye, which consists in castingthe eye, forming on the eye a sand core, so that the eye constitutes aninterior supporting-bar for the sand core, forming a patterncorresponding to the hook, thesand core, and the eye, pressing thispattern into sand to form a corresponding cavity, placing the eye, withthe sand core, into the part of the cavity corresponding to the eye andsand core, casting the hook with its link extending round the sand core,pressing a pattern into sand to form a cavity corresponding to the eye,the hook, and the object to be secured to said eye, plac ing said eyeand hook into the proper part of the cavity, and finally casting theobject into the part of the cavity corresponding to said object.

In testimony whereofl have hereunto set my hand and seal in the presenceof two subscribing witnesses CHARLES L. SAGE. [L s] Witnesses:
